Can't power on
display show gray color background only
If you are not even getting so much as an icon on your display indicating a disk issue, try performing an SMC and PRAM reset. If that does not alleviate the problem, take it in to an Authorized Service Center, or Apple Store Genius Bar.
You may try booting into Safe Mode, by holding down the shift key, while booting (in case it is booting part way, then hanging). Alternatively, try and boot to your Recovery Partition by holding down the OPTION key while booting, and see if Boot Manager lets you choose the Recovery Partition. If so, run Disk Utility and Repair Permissions & Repair Disk.

My ipad hangs up after showing a message that says it "Cannot Access Find My Friends" and that I need to open the app and review my signin info to continue sharing. I can't go there because it is hung up. I also can't power off.
Perform a Reset...

Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Release the Buttons.

My iPod touch 4 generation 32gb sometimes is really slow.When ever my iPod is being slow and I get on an app the app will shut down. My lock botton is broken and I use the accesery botton to lock it. That being said I can't power down my iPod. I need help, I don't know what to do! Could you tell me how I can power down my iPod or how I can fix the slowness and the shutting down of the apps.
- Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
- Next, reset the iPod
To reset the iPod without the hardware buttons,
Reset network settings: Settings>General>Reset>Reset Network Settings. All your wifi and bluetooth preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected. You will have to rejoin wifi networks and repair BT devices
Then you can try:
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device. -
My lock screen is frozen! It will not let me slide to unlock or touch the screen at all. I can't power it down either because the lock button is broken. A friend of mine said I might need a new Digitizer? Is there anyway I can avoid that? Pleasae Help!
I am having the SAME exact problem! Except instead of lock button broken it's my home button so I can't do the whole "put in recovery mode" deal. My screen only says "tap the home button 3 times" and it has my screen locked until I hit the home button but since it is broken I can't get in my phone at all. I have all of my work info in my phone so I'm screwed and can't get any help. PLEASE let me know if you find a way around this...!!!
Thanks! -
I received an error while updating my phone to ios6. Now it's frozen and I can't power down or reconnect it to show in iTunes. What do I do?

Just tried to update my iPad 2 to the current iOS, and I got an error that said the update wouldn't install. The iPad is stuck in a funny mode with the apple and spinning wheel showing. I can't power it down or restart it. What next? Thanks.
Try a hard reset: hold the power and home buttons simultaneously until the Apple logo appears.

Where can high-power video cards be installed on a first-gen Mac Pro?
I have a first-gen Mac Pro with a Radeon X1900 XT in Slot-1 and a Geforce 7300 GT in Slot-4. The x1900 XT powers a 30" monitor and the 7300GT powers 2 x 20" monitors. The 7300GT card died and is being replaced with an 8800 GT.
Now it seems fairly obvious that for gaming the 8800 GT is superior to my X1900 XT. Ideally I'd like to just throw my new 8800 GT in Slot-1 and use it for my 30" monitor and then run the 2 20's off the X1900 XT in Slot-4. The problem with that is that the x1900 XT is a huge card and physically won't fit in Slot-4 because it runs in to the hard drives above it.
*Now, on to the questions / clarification:*
_Question 1_: Is the first-gen Mac Pro the same as the new Mac Pro in that high-power cards can only be used in Slot-1 and Slot-2? If so, why does it come in the standard configuration of:
Slot-1: x16
Slot-2: x1
Slot-3: x1
Slot-4: x8
It would seem that Apple purposely did this so you would run 2 high-power cards in Slot-1 and Slot-4 and keep them away from each other for heat reasons. The new Mac Pro has x16 bandwidth on Slot-1 and Slot-2 and it would make sense why they say to only install high-power cards in Slot-1 and Slot-2 for it.
_Question 2_: PCI-e configurations. There are a few ways I could tweak the configuration of the expansion slots to make this setup work. I'm curious as to which you would think is best:
*Option 1 (default PCI-e config, only works if a high-power card can be installed in slot 4):*
Slot-1: x16 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-2: x1
Slot-3: x1
Slot-4: x8 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Now, the first issue is can the 8800 even run in Slot-4 due to the supposed power problem? If so, would there be a difference in performance for gaming at x8? I know this is backwards because you'd want the "primary" card to run on x16 but that's just not possible with this PCI-e configuration. If there is a difference in performance would an 8800 GT at x8 still run significantly faster in games than an X1900 XT a x16? I'd think so, but that's assuming the x8 isn't a real bottleneck.
*Option 2 (the only solution if the cards have to be installed in the first 2 slots):*
Slot-1: x8 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Slot-2: x8 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-3: x4
Slot-4: x4
You still have the issue of the 8800 only running at x8 (if it even makes a difference, not sure). The benefit I see here is that instead of the X1900 XT dumping all of it's heat in to the 8800 GT (since heat rises) you have the 8800 GT on the bottom where it might run cooler. The X1900 XT would then also be limited to x8 but it's not even being used for gaming so it wouldn't matter at all. The X1900 XT is huge and would cover up Slot-3 but I don't use the other 2 slots so I don't mind.
*Option 3 (only works if Slot-3 can actually power an X1900 XT):*
Slot-1: x16 - GeForce 8800 GT - 30" monitor for major tasks / gaming
Slot-2: x1
Slot-3: x4 - Radeon X1900 XT - 2 x 20" monitors for minor tasks / programs
Slot-4: x4
This seems ideal only because this is the only setup that can get the 8800 to run at x16. The issue now is can Slot-3 run a high-power card? The card doesn't really NEED the power since it's just for running basic apps and not gaming. Again, the X1900 would cover up Slot-4 but it's not being used so no worries there.
*At the end of the day, the most important thing to figure out is:* where can high-power cards be installed in a first-gen mac pro? Once we know that we can figure out Question 2. The instructions that come with the 8800 GT say it can be installed in any of the 4 slots, but I don't know if I really believe that.
Thanks in advance for your help!Thanks for your help, I think we've beat this horse to death :P. I'm glad I got it all figured out though.
Now the only question is if the gaming performance of the 8800 is actually enough better than the X1900 to warrant making it my "primary" video card. As long as Adobe CS3 apps don't rely on core image like some of the Apple Pro apps do I think it will be fine. If they do I'd have to probably just stick with the X1900 since I use CS3 every single day and only play video games once a week if I'm lucky.
What are your thoughts on the X1900 vs the 8800 GT for CS3?
Edit: This just occurred to me... Since I'm going to have to run them as x8, x8, x4, x4 there isn't really going to be a "primary" card since neither will be at 16x. I guess I could technically just plug my 30" monitor in to either one of them depending on what I feel like doing. If I'm going to play a game I just plug in to the 8800 and if I'm working I plug in to the 1900. The computer is up on the desk so moving the monitor from one card to the other takes about 10 seconds. I could just plug 1 20" monitor in to each so there's always a free DVI port on either one.
It's not the most elegant but I guess it would be a good compromise if I wanted the "best" performance in either situation. I realize the Radeon 3870 is probably the best of both worlds but I really don't want the noise. I already modified my 1900 with this after 6 months of listening to the lawn mower that was the stock 1900 cooler: http://www.arctic-cooling.com/vga2.php?idx=147
I'm just hoping the 8800 isn't too loud . -

thanks a lot!Hi
Just alter the device from hda to hdb
eg
from
disk = ['file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/system.img,hda,w',
'file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/oracle10g_x86.img,hda,w',
',hdc:cdrom,r'......
to
disk = ['file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/system.img,hda,w',
'file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/oracle10g_x86.img,hba,w',
',hdc:cdrom,r' .......
this way you mount you system image root volume as a device [hda]
and your oracle10g image as a device [hdb]

[Help]How can I power on or power off the specpum through GPIB by VC6.0 ?
[帮助]如何在VC6.0环境下通过GPIB卡开关频谱分析仪的电源？
For this is my first programme, thus ,I have no idea how to write code, and don't know the heaer files and DLL files to be included or imported.
因为这是我写的第一个程序，所以，不知道如何写代码，也不知道需要引用或者导入哪些头文件或者库文件。
Thank you ！
谢谢！Your question is very abstract, and difficut to understand what you want to do. Do you wish to control your spectrum analyzer for TURN-ON and TURN-OFF power?
Assuming your question is so...
To turn the instrument power OFF, you should look for the GPIB command that can do this in the instrument's operation manual.
To turn the instrument power ON, it is very difficult or almost impossible to do so, because your app program will have no way to communicate with your "unpowered" instrument. -
My iPad mini is locked due to the "no backup in past 2 weeks message." I can't power it off or get rid of this message. HELP!
Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Can a power mac G5 ver.10.4.11 upgrade to Leopard 10.5
can a power mac G5 ver.10.4.11 upgrade to Leopard 10.5
Yes, but you will have to find an installation disk some place like Amazon or eBay, Apple no longer stocks it.
Be sure to buy a retail version, black face with large silver X, and not the machine-specific grey face disk. -
URGENT: iphone 4 hang, can't power down, can't receive calls, can't do anything
I've been using my iphone 4 for more since I got it when it came out 1.5 yrs ago with hardly any problems.
I updated to OS5 few weeks back and was totally Ok until today, I started my gmail, and the phone froze and the swirling symbol is going next to my full WiFi Access and ATT 2 bars signal strength.
It's been more than 30 mnts, and can't receive calls, can't power it down, and nothing I pressed or did seems to affect the device.
What do I do?Well, first, you can't revert back to OS 4.x, and second, a search of the forum will quickly show you that this could happen with 4.x, 3.x, 2.x and ever the original iPhone Classic.
And don't think of the iPhone as a phone; it's a very powerful pocket sized computer that can also make phone calls. And it can suffer all of the things that happen to any computer, like the Windows Blue Screen of Death and the Mac OS X kernel panic (which is what happened). It happens when memory gets full (RAM, not storage) or when one app steps on the memory of another. You can minimize the chance of it happening by turning the phone off occasionally, which shuts down all of the apps. -
I bought my iPhone 6 plus in Boston, but now I went back to China, unfortunately, my iphone can't power on, but Apple support in China refuse to change new one because I bought it in US, so could you give me help or contact with me?
Thank you for your response.
Yes, it is full, I went to apple support in China, they told me it was hardware problem, it need to change a new machine!
Did you know the email about US apple support department, it is hard to call them when I am in China now. -
